QuestionAnswer
What are the standard connections 15 mmID (inside) for ET tube, or trach tube and 20 mmOD (outside)for resuscitation mask
Uses for bag Ventilate patients during CPR, hyperventilate before and after suctioning, ventilate during transport, management of mechinially ventilated patients
What does FIO2 depends on oxygen input flow, reservoir volume, delivered stroke volume and rate, bag refill time
Parts of Bag patient valve, bag, inlet valve, oxygen nipple, reservoir, pressure pop-off
Size of adult bag 1500-2000 ml volume no pressure pop off needed
Size of pediactric bag 250-500 ml volume Pressure pop off at 40 cmH20 pressure (+-10 required)
Size of neonate bag 250 ml volume comes with 40 cmH20 pressure (+-5 cmH20 pressure pop-off)
Ideal stroke volume for Adult 800 ml avg (1500-2000 max)
Ideal stroke volume for infant 240 ml
Spring loaded mechanism NOT sensitive to patient effort and spontatneous breathing WILL NOT open valve to allow patient to breath from bag
Diaphragm (duckbill) these valves are flexible and EASILY OPENED by pressure from bag compression, or by the pt spontaneous breathing effort
Diaphragm (leaf) spontaneous breathing WILL open valve to allow patient breath from bag
Charcteristics of good self inflating bag Easy to clean..standard connections...self inlfating.. nonrebreathing valve...available in different sizes
Function of pop off valve (pressure relief valve) prevents delivery of excessive pressure with infants/pediactrics pts.
Effect of ventilation on RATE Faster=lower FiO2.....Slower = increased FiO2
Effect of ventilation on O2 FLOW higher the flow = increased FIO2 slower the flow = decreased FIO2
Effect of ventilation on Reservoir capacity no reservoir = 35-40 % at O2 flow of 10-15 lpm...up to 100% at O2 flow of 10-15 lpm... size of reservoir = increased size - Increased FIO2 reservoir present =
Effect of ventilation on REFILL TIME increased time = increased FIO2 decreased time = decreased FIO2
Effect of ventilattion on STROKE VOLUME (squeezing) increased stroke volume = decreased FIO2 decreased stroke volume = increased FIO2
Observations to assure ventilation rise and fall of chest, breath sounds, ABG, and oximetry
Hazards with bags gastric insufflation, vomiting/aspiration, barotrauma, hypoventilation
What to do if you get gastric insufflation intubate ASAP
what to do if vominting or aspiration occurs intubate ASAP, this causes decreased compliance (expansion stiffens)
What to do if barotrauma happens don't squeeze bag until pop-off--slow down and not as hard
what to do if hypoventilation occurs use both hands, and check for breath sounds
Advantage for mouth to mask ventilation no direct person to person contact
Limitations for mouth to mask ventilation maintain airtight seal, gastric inflation
Demand valve gas powered, pressure relief set at 40, you get 100% FIO2 with 50 psi outlet, THEY CAN GENERATE A BREATH
PEEP valves used to keep back pressure open...pressure to overcome refractory hypoxemia (decreased FRC) (it's not responding to oxygen help
Hazards for demand valve barotrauma because you won't feel compliance, tank runs out to fast, limits pop, don't know tidal volume
